Magento2 and AWS ElastiCache setup

Question

I have a Magento 2 based website on an AWS EC2 and a AWS RDS . I would like to setup AWS ElastiCache Redis however the only information I found is for Magento 1 and written back in 2014 that says I would end the app/etc/local.xml file

So my question is how would I write the needed code to go into the app/etc/env.php file which is I believe where I would need to edit. I believe I need to edit the section of the file that reads

'session' => 
 array (
 'save' => 'files',
 ),

However I am not sure what to replace that with.

thanks

during installation, I simply put the RDS endpoint DB name and DB details like the master user name of aws RDS , etc. it's get connected perfectly.
